ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 277,911, dated May 22, 1883.

A Application filed September 30, 1882. (ModeL) 4 is a side view of part of the skate, showing a modified form of bracket. Fig. 5 is a perspective view of said modified form of bracket.

This invention relates to a new manner of joining the rollers to the foot-board ofa skate; and it consists in the employment, for this purpose, of certain spring-brackets which are made of wire, and which are fastened by pins to the foot-board, all as hereinafter more fully described. By making these brackets of wire, bent in the peculiar manner in which I bend them the advantages are gained of simplicity of construction, economy, strength, and light ness, and the foot-board which supports these brackets is further pressed by them.

Inthe drawings, the letter A represents the foot-board of a rollerskate.

B is the front roller or set of rollers, and O the rear roller or set of rollers. Each of these rollers is hung in abracket, D, there being two such brackets shown on the same skate. Each bracketD is made of steel wire bent into the general form of a letter U, when looked at from the end, as in Fig. 3, and made to straddle the foot-board A, so that the middle and upper portion, a, of the bracket rests on the foot-board. At the sides of the foot-board.

the bracket is formed into coils 12, through which the fastening pin or bolt dis inserted. The same pin, d, can pass through both coils b of one bracket to hold the bracket firmly in place. The lowerendof each bracketis formed into eyes 6, in which the axlesfof the wheels have their bearings. Between the coils b and the eyes 0 the bracket inclines backward, as shown at h. The upper portion, a, of the bracket rests against a shoulder, g,in the footboard, which shoulder is either formed by grooving the foot-board or by a separate projection therefrom.

It will be readily seen that the brackets D,

formed of the parts a bh 6, can be readily bent.

in a machine into the form shown, andthat their attachment to the foot-board is very easy, as it is only necessary to insert the pin d through the coils b, and through the perforation previously made for its reception in the foot-board. The brackets straddling the footboard strengthen the same, and the portions 7 h, which are below the foot-board, are springy, giving elasticity to the skate.

In Figs. 4 and 5 is shown a modified form of bracket, in which the part a is carried nnder instead of over the foot-board A, bearing against it, so as to constitute an additional spring.

I claim- 1. In a roller-skate, the straddling brackets D D, placed over the foot-board and connected with the axles of the skate-rollers, substantially as described.

2. The bracket D, constructed with the top portion, a, side coils, b, inclined parts It, and

lower eyes, c, for use on a roller-skate, substantially as specified.

3. The straddling bracket D, constructed substantially as described, in combination with the foot-board Act a roller-skate, and with the front support, 9, on said foot-board, substantiallyas herein shown and described.

4. The combination of a foot-board of a roller-skate with the roller-carrying wires h it, having eyes I) at their upper parts and eyes 6 at their lower parts, and with the fasteningpin d, passing through said eyes I), substantially as herein shownand described.
